AUTOMATIC OILER FOR STOCK.

Specification of Letters Patent. Patented J 113 13, 1916,

Application filed A riis, 191s. anae ia.

To all whom it may concern} p Be it known that I, WILLIAM-H- KREM- k sun, a citizen of the United States, residing gas at Fremont, in the county of Dodge'an State of Nebraska, have invented certain new and useful Improvements in Automatic Oilers for Stoclnof which the following is a specification. ,7 7 This invention relates to an automat c oiler for use in applying medicated liquids to hogs, sheep or cattle for destroying parasites or curing skin dlseases, and has for lts I object, broadly, to provide such a construction that a positive operationmay be effected for applying the liquid forcibly to the body of the animal.

The invention includes a passageway through which the animal may travel, and a door or gate arranged to partly obstruct the passageway, and an ejector member for applying the liquid,.operative by the swing ng movement of the gate when the animal makes contact therewith in the act of moving through the passageway.

The device has been found tobe particularly useful in connection with the raising of hogs and sheep, the application of the liquid being positive in operation since the door or gate may partly obstruct a w'ay5between feeding yards, through which ,the stock will readily pass.

The invention consists of the novel construction, combination and arrangement of parts as described herein and claimed, and as. illustrated n the accompanying draw ng,

it being understood that changes in form, size, proportion and minor (161551-118 may be made within the'scope of the invention as determined by the appended claims, without sacrificing any of its advantages.

In the accompanyingdrawing, illustrat ing one embodiment of the invention, Figure 1 is a View in side elevationofanoiler for stock. Fig. 2 is an enlarged detaihpartly in section, relating to Fig. 1,the;ejector and receptacle being partly broken away. Fig. 3 is a vertical section on line 3.3 of Fig. L Fig. l is a vertical section online 4-4 of Fig. 1,'- looking to the ejector and receptacle. Fig. 5 is a view of the ejector in longitudinal section. Fig. 6 is a plan view of a segmental actuating plate. Fig. 7 is a perspective View of one of the crank shafts. 'Figs58 and 9,

. respectively, are sideand end views offthe same, Fig. 9 showing the free end of the tubular sections 12 and 13 to advantage,

finger-on said crank shaft. Fig; 10 is a plan view of a tread block employed. 7

Referring now to the drawing for a more particular description, I provide a doorway 1-1 which mayhave any desired height and width depending upon the kindof; stock to :be treated, and while any suitable-inaterial may be used to providea' rectangular frame or doorway, I,haveemployed the vertical these being connected at their upper ends with-the horizontal, tubular sections 14 and 14, the lower ends of said vertical sections being secured to a suitable base or platform 15. The frame thus described provides a structure which is strong and portable, and c tiv n xpen i I provide agate of rectangular form,

preferably consisting, in part, of the top and bottom tu-bular sections ;16 and 17, andside tubular sections 18 and 19, their ends being 7 suitably 'joined or connected to. provide va rigid structure. In order that the gate will remain normally closed and, normally, will be disposed; in horizontal alinement with the standards or posts 12 andl3, lprovide forthe post'12 a tread block120 having an inclined, annulartrackway 21 disposed; equidistant from the longitudinallaxis of-said post, upon which trackwayf the wheel 22 may move, said wheel having bearings in a-block23 which is securedto the-gate. The gate is provided with sleeves 24 for engage ingloosely the p0st'12, and it will be understood thattwhen the gate is swung ineither direction, it will beelevated' for the reason that thewheel will move upwardly 1 upon the annular trackway when the gate swings outwardly, and the gate will -move down wardly when swung to a closed position, its

weight causing said closingmovement, the

operate in such amanner that when an animal causesa swinging movement of the gate,

cated liquid, and devicesare providedwhich p outwardly, in either direction, quantities of the liquid, either as a limited stream or spray, will be discharged, the arrangement preferably being such that successive charges of the liquid will be applied upon and at difierent parts of the body of the moving animal. r

At 27 is indicated a cylinder provided at its outer and inner ends respectively with screw caps 28and 29, the cap 29 being provided with a nozzle or screw plug 30 to provide an inclined exit-way or discharge port 31for liquid, andproviding a valve seat 32 for the needle Valve 33, the stem 33 of the valve being slidably mounted in the screwcap28and provided with a piston to and provided upon its'threaded' end, inwardly'of cap 28, with an adjusting-nut 34. Any suitable conduit may be providedthrough which the liquid may move from the receptacle 26 to the cylinder, the bore of pipe 14, as best shown in Fig. 2, being used for this purpose,

, the liquid moving into the cylinder through an aperture 35 formed in the wallof said cylinder and opening upon the boreof said pipe.

Means are providedfor reciprocating the valve stem while an animal is causing a swinging movement of the gate outwardly when moving through the passageway. An actuating plate 36 is provided, said plate beverse curvature'so that its ends, at the sides of the tubular section .16 maybe disposed somewhat lower than its middle. This plate is mounted midway between its ends upon the tubular section 16 of the gate and suitably secured thereto.- -As best shownin Fig.

6, this plate is provided, toextend upwardly near its curved edge at one side of the tubular section 16 (for convenience called the frontside) with aseries of projections or teeth 37 ,these projections being disposed at suitable distances apart in a curved row concentric with the center of the segment or post 12 which iszthe center of movement for the gate, and said segment is provided with a series of projections or teeth 38, similar to those already described, and disposed in a row concentric with the center of movement of the gate, but somewhat nearer the center than the series of teeth 37 ,and at the opposite 'ornear sidev of the tubular section 16.

I Secured upon the tubular section 14 ofthe gate frame is a b01139 which provides bearingsfor a pair of crank shafts4O and 41,

said crankshaft 40 having an arm a extend ing transversely therefrom, said arma be ingdisposedin the-planeof and adapted to beenga'ged bythe series of teeth 38, in suecession, when the gate swings outwardly at the rear side of the gateway; The-crank shaft 41 also is provided'with a transverse arm :6 disposed in the planeof and adapted to beengaged in successiong by the series of teeth or projections 37 of said plate 36 when the gate has a swinging movement-in an opposite direction to that last mentioned.

The crank 0 of crank shaft 40 is provided with a finger d which is disposed transversely with reference to said crank, the terminal part of said finger d being ,disposed near the lower end and at the front side of the cylinder 27.' Crank 0 of the crank shaft 41 is also provided, to extend transversely therefrom, with a finger 6, its terminal part being disposed at the opposite or rear side of said cylinder.

Numeral 42 indicates a tilting member of substantially inverted U-shape, the end 'of each of its arms being provided with a foot piece'or'bufifer, these being indicated, respectively, at 43 and 43, for engagement with the respective fingers d and 6. At 44, mounted on the threaded end of the valve stem outwardly of the upper end of member 42, is a second nut, by meansof which any upward movement of the tilting member will be communicated to the valve stem 33, the arms of said member 42 sliding in the guide 45 which is secured to the cylinder by suitable keepers '46.

v In operation, a hog or other animal may cause a swinging movement ofthe gate ina manner to cause the arm I) of the crank shaft 41 to engage, in succession, teeth 37 of the plate 36, "and each engagement mentioned -will cause a part rotation of the crank shaft 41 to effect a swinging movement of the finger e which will elevate the tilting memher for lifting the valve from its seat, the

liquid thereupon moving out of the discharge port with considerable force, the weight of the metallic parts, such as members 33,33, 42 and 44 being depended upon for causing a return movement of the valve, forcibly, to its seat for ejecting the liquid from port 31.

Numerals 47 indicate weights with which arms a and b of the crank shafts are provided, so that, after a swinging movement has been eflectedfor one of said arms, by its engagement with a tooth, it will instantly move or swing downwardly to be engaged by the next tooth-of the series. Suitable brace rods 48 are provided which extend between the plate 36 and the tubularsection 19 of the gate,for the purpose of supporting said plate. I

From the description it will be understood that the amount of discharge, while an animal is moving throughthe gate frame or passage way may be increased or diminished, as emay be desired. Member 42, by means of the adjustments mentioned, may be elevated or lowered on the stem 31 to cause, respectively, a decrease or increase of the quantitydischarged; also it will be understood that when the teeth of one series are moving into engagement with oneYof the 13Q arms a or b, the teeth of the other series do not engage either of'the arms, the arrangement being such that operation will be effective for spraying or applying liquid from a stationary nozzle or ejector to different parts of the body of the animal while passing through the gateway. It will be appreciated that if the gate has a rapid swinging movement caused by a 10 rapid movement of the animal, that the intervals of time between the discharges will be correspondingly reduced, so that the discharges of the medicated liquid may be practically applied to different parts of the body of the moving animal.

7 Having described construction of parts, a further explanation relating to operation is not necessary.
